Purpose Reactive oxygen species (ROS) are generated as an indirect product of radiation therapy (RT). Genetic variation in genes related to ROS metabolism may influence the level of RT-induced adverse effects. We evaluated the potential association of single nucleotide polymorphism (SNP)–related response to radiotherapy injury in breast cancer patients undergoing RT. Materials and Methods Eighty patients receiving conventional RT were included. Acute effects were evaluated according to the Radiation Therapy Oncology Group (RTOG) scores. DNA was extracted from blood and buccal swab samples. SNPs were genotyped for GSTP1, GSTA1, SOD2, and NOS3 genes by polymerase chain reaction–based restriction fragment length polymorphism. Univariate analysis (odds ratios [ORs] and 95% confidence interval [CI]) and principal component analysis were used for correlation of SNPs and factors related to risk of developing ! grade 2 acute effects. Results Sixty-five patients (81.2%) showed side effects, 32 (40%) presented moderate to severe acute skin toxicity, and 33 (41.2%) manifested minimal acute skin reactions by the end of treatment. In both univariate and multivariate analyses, nominally significant associations were found among body mass index (OR, 3.14; 95% CI, 8.5338 to 1.1274; p=0.022), breast size (OR, 5.11; 95% CI, 17.04 to 1.54; p=0.004), and grade ! 2 acute radiation skin toxicity. A significant association was also observed between NOS3 G894T polymorphism (OR, 9.8; 95% CI, 211.6 to 0.45; p=0.041) and grade ! 2 acute radiation skin toxicity in patients with neo-adjuvant chemotherapy treatment. Conclusion The analysis of the factors involved in individual radiosensitivity contributed to the understanding of the mechanisms underlying this trait.

In this paper, we investigate homomorphisms in proper JCQ^{*}-triples and derivations on proper JCQ^{*}-triples associated to the following Pexiderized functional equation [f(x+y+z) = f_{0}(x)+ f_{1}(y)+f_{2}(z)]. This is applied to investigate homomorphisms and derivations in proper JCQ^{*}-triples.

<P>Objective: To evaluate the anti-hyperglycemic potential of sinigrin using in vitro, in silico and in vivo streptozotocin (STZ) induced hyperglycemic zebrafish model. Methods: The in vitro enzyme inhibition assay was carried out to determine the IC50 value against alpha-glucosidase and alpha-amylase, in silico molecular docking was performed against both enzymes with PyRx tool and simulations were performed using GROMACS tool. Hyperglycemia was induced in zebralishes using three intraperitoneal injections on alternating days for one week at 350 mg/kg of STZ. Hyperglycemic fishes were treated intraperitoneally with 50, 100 and 150 mg of sinigrin/kg of body weight for 24 h and glucose levels were measured. Results: The sinigrin showed very strong inhibition against alpha-glucosidase and alpha-amylase with 0.248 and 0.001 24 mu M while reference drug acarbose showed IC50, value of 73.0700 and 0.0017 mu M against alpha-glucosidase and alpha-amylase, respectively. Kinetic analysis revealed that sinigrin has the mixed type mode of inhibition against alpha-glucosidase. Molecular clocking results revealed its strong binding affinity with alpha-glucosidase (-10.00 Kcal/mol) and alpha-amylase (-8.10 Kcal/mol). Simulations graphs confirmed its stability against both enzymes. Furthermore, in hyperglycemic zebrafishcs most significant (P<0.001) reduction of glucose was occurred at 150 mg/kg, moderate significant reduction of glucose was observed at 100 mg/kg and no any significant reduction of glucose was measured at 50 mg/kg. Conclusions: It can be evident from the present results that sinigrin has potent anti-hyperglycemic activity and it may prove to be effective treatment for the hyperglycemia.</P>

<P>The ALICE Collaboration at the LHC has measured the J/<I>ψ</I> and <I>ψ</I>′ photoproduction at mid-rapidity in ultra-peripheral Pb–Pb collisions at [FORMULA OMISSION].</P><P>The charmonium is identified via its leptonic decay for events where the hadronic activity is required to be minimal. The analysis is based on an event sample corresponding to an integrated luminosity of about 23 μb<SUP>−1</SUP>. The cross section for coherent and incoherent J/<I>ψ</I> production in the rapidity interval −0.9<<I>y</I><0.9, are [FORMULA OMISSION] and [FORMULA OMISSION], respectively. The results are compared to theoretical models for J/<I>ψ</I> production and the coherent cross section is found to be in good agreement with those models incorporating moderate nuclear gluon shadowing at Bjorken-<I>x</I> around 10<SUP>−3</SUP>, such as EPS09 parametrization. In addition the cross section for the process <I>γγ</I>→<I>e</I><SUP>+</SUP><I>e</I><SUP>−</SUP> has been measured and found to be in agreement with models implementing QED at leading order.</P>

<P>An inexpensive sol-gel technique to synthesize TiO2-Fe2O3 nanocomposites with improved structural and photochemical properties is introduced. A series of TiO2-Fe2O3 nanocomposites with different Fe2O3 contents were prepared through cheap TiO2 precursor titanium oxychloride (TiOCl2). The physicochemical properties of the samples were examined by XRD, XRF, SEM, EDX, HRTEM, UV-vis DRS, FTIR, TGA and nitrogen gas physisorption studies. The effects of calcination temperatures and Fe2O3 content on the mesostructure and photocatalytic strength of the prepared TiO2-Fe2O3 composites were investigated. Results showed that composites with distinct structural, optical and photochemical properties can be formed by varying Fe2O3 content.

<P>A sol-gel technique has been developed for the synthesis of a magnetite-silica-titania (Fe3O4-SiO2-TiO2) tertiary nanocomposite with improved photocatalytic properties based on the use of inexpensive titania and silica precursors. The exceptional photocatalytic activity of the resulting materials was demonstrated by using them to photocatalyze the degradation of methylene blue solution. The best formulation achieved 98% methylene blue degradation. An interesting feature of the present work was the ability to magnetically separate and reuse the catalyst. The efficiency of the catalyst remained high during two reuses. The synthesized nanomaterials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier transform infrared (FTIR) spectroscopy, ultra-violet-visible spectroscopy, diffuse reflectance spectroscopy, and thermogravimetric analysis. XRD analysis revealed the formation of multicrystalline systems of cubic magnetite and anatase titania crystals. SEM and TEM characterization revealed well-developed and homo-geneously dispersed particles of size less than 15 nm. FTIR spectra confirmed the chemical interaction of titania and silica. It was further noticed that the optical properties of the prepared materials were dependent on the relative contents of their constituent metal oxides.</P>

이정곤,G. Senel,Young Bae Jun,Fadhil Abbas,Kul Hur 원광대학교 기초자연과학연구소 2021 ANNALS OF FUZZY MATHEMATICS AND INFORMATICS Vol.22 No.2
Our aim of the research is to study two aspects: First, we define new concept (called an {\it interval-valued soft set}) which combines an interval-valued set with a soft set, and discuss with its algebraic structures and give some examples. Second, we investigate basic topological structures based on interval-valued soft set, for example, subspace, base and subbase, neighborhood, closure and interior, and give some examples.
STABILITY OF DERIVATIONS ON PROPER LIE CQ<sup>*</sup>-ALGEBRAS
Najati, Abbas,Eskandani, G. Zamani Korean Mathematical Society 2009 대한수학회논문집 Vol.24 No.1
In this paper, we obtain the general solution and the generalized Hyers-Ulam-Rassias stability for a following functional equation $$\sum\limits_{i=1}^mf(x_i+\frac{1}{m}\sum\limits_{{i=1\atop j{\neq}i}\.}^mx_j)+f(\frac{1}{m}\sum\limits_{i=1}^mx_i)=2f(\sum\limits_{i=1}^mx_i)$$ for a fixed positive integer m with $m\;{\geq}\;2$. This is applied to investigate derivations and their stability on proper Lie $CQ^*$-algebras. The concept of Hyers-Ulam-Rassias stability originated from the Th. M. Rassias stability theorem that appeared in his paper: On the stability of the linear mapping in Banach spaces, Proc. Amer. Math. Soc. 72(1978), 297-300.
